Best open-source headless commerce frameworks for TypeScript teams
2 models · updated 2026-09-09
The verdict
Medusa leads — All 2 models rank Medusa the top pick.
As of 2026-09-09, Claude and Gemini collectively rank Medusa #1 for open-source headless commerce frameworks for typescript teams on ModelsAgree — unanimous among the 2 models that have answered. The models' case: v2 is TS-native end to end (Node/TypeScript modules, workflows engine, admin), MIT-licensed with no open-core lock. The models' main caveat: You operate it yourself — v2 is young enough that some modules/plugins lag the core, and there is no first-party managed cloud, so ops burden and. The strongest alternative is Vendure — Mature, disciplined NestJS/TypeScript backend with a strong typed GraphQL API, a well-designed plugin system, and genuinely solid.

Combined ranking
- 1Claude #1Gemini #1
v2 is TS-native end to end (Node/TypeScript modules, workflows engine, admin), MIT-licensed with no open-core lock; the modular architecture lets teams swap payment/fulfillment/pricing providers cleanly, and its module + workflow model is the most idiomatic fit for a TS team that wants to own custom commerce logic rather than fight a rigid schema. Largest active JS/TS commerce community and plugin ecosystem, self-hostable with no vendor gate.

Largest active JS/TS commerce community and plugin ecosystem, self-hostable with no vendor gate.
Gemini Native TypeScript throughout with a modular architecture, featuring an integrated workflow orchestration engine with automatic rollbacks, flexible Data Modeling Language (DML), RESTful APIs with typed SDK generation, and a large ecosystem for custom commerce logic. Near-tie with Vendure; rank assumes the typical team prioritizes rapid development, modular service swapping, and REST ergonomics over rigid GraphQL contracts.
Where it falls shortper Claude You operate it yourself — v2 is young enough that some modules/plugins lag the core, and there is no first-party managed cloud, so ops burden and upgrade churn fall on your team.
per Gemini Historical major releases introduced substantial architectural rewrites with painful migration paths, and it lacks native GraphQL support; not for teams requiring long-term frozen API contracts without maintenance overhead or strict compile-time GraphQL schemas.

Mature, disciplined NestJS/TypeScript backend with a strong typed GraphQL API, a well-designed plugin system, and genuinely solid multi-channel/multi-currency and complex tax/promotion handling out of the box; excellent docs and backward-compatibility record make it the safest choice when correctness and long-term maintainability of the backend matter more than breadth of ready-made integrations.

Claude Mature, disciplined NestJS/TypeScript backend with a strong typed GraphQL API, a well-designed plugin system, and genuinely solid multi-channel/multi-currency and complex tax/promotion handling out of the box; excellent docs and backward-compatibility record make it the safest choice when correctness and long-term maintainability of the backend matter more than breadth of ready-made integrations.
Gemini Built natively on TypeScript and NestJS around a GraphQL-first architecture, delivering exceptional code discipline, dependency injection, and end-to-end type safety spanning database entities, admin UI extensions, and storefront APIs. Near-tie with Medusa; rank assumes slightly higher onboarding overhead due to NestJS patterns and GraphQL boilerplate compared to Medusa's REST-driven workflows.
Where it falls shortper Claude GraphQL-only and opinionated NestJS conventions mean a steeper ramp; smaller plugin marketplace than Medusa, so you build more integrations yourself, and the storefront is entirely your problem.
per Gemini The opinionated NestJS and GraphQL architecture imposes rigid structure and higher initial boilerplate; not for teams seeking lightweight REST endpoints, rapid unopinionated scripting, or teams without GraphQL expertise.

Battle-tested, high-scale GraphQL-first platform with the most complete enterprise feature set here (webhooks/apps architecture, permissions, multi-warehouse, taxes); its App SDK and storefront are TypeScript/React, so a TS team consumes a clean typed API even though the core is elsewhere. Strong for large catalogs and complex B2B/B2C.

Claude Battle-tested, high-scale GraphQL-first platform with the most complete enterprise feature set here (webhooks/apps architecture, permissions, multi-warehouse, taxes); its App SDK and storefront are TypeScript/React, so a TS team consumes a clean typed API even though the core is elsewhere. Strong for large catalogs and complex B2B/B2C.
Gemini An enterprise-grade, battle-tested open-source headless commerce engine providing a comprehensive GraphQL schema, advanced multi-channel/multi-warehouse management, and a first-class TypeScript developer experience via the official Saleor App SDK, CLI, and Next.js starters. Rank assumes the team values mature, turnkey core commerce features over having backend internals written in TypeScript.
Where it falls shortper Claude The core server is Python/Django, not TypeScript — you cannot customize backend logic in TS, only via apps/webhooks; heavier to self-host and its licensing/commercial tiering makes the fully-open path less generous than Medusa or Vendure.
per Gemini The core engine is built with Python and Django rather than TypeScript, precluding in-process TypeScript plugins or direct code-level modifications; not for pure TypeScript teams unwilling to manage external webhook apps or a multi-language stack.

Best-in-class open-source TypeScript storefront framework (React/React Router, Oxygen deploy) with first-party components, caching, and typed Storefront API access; if the team wants a headless front end on a managed commerce backend, nothing else matches its polish, performance defaults, and support.

Claude Best-in-class open-source TypeScript storefront framework (React/React Router, Oxygen deploy) with first-party components, caching, and typed Storefront API access; if the team wants a headless front end on a managed commerce backend, nothing else matches its polish, performance defaults, and support.
Gemini A high-performance, open-source headless storefront framework built specifically on React Router/Remix and TypeScript, offering commerce-tailored runtime primitives, edge caching, sub-second buyer journey performance, and official Storefront API utilities. Rank assumes the team wants headless frontend speed and flexibility while deliberately offloading backend operations to managed infrastructure.
Where it falls shortper Claude It's a storefront layer, not a headless backend — it's tightly bound to Shopify's commerce engine and hosting, so it fails the "own your stack / self-hosted OSS platform" test entirely.
per Gemini It is exclusively a frontend presentation layer tightly coupled to Shopify's proprietary, closed-source SaaS backend, providing no self-hostable commerce engine or database ownership; not for teams requiring a fully open-source, self-hosted commerce backend or sovereign data control.

A mature, production-proven open-source headless commerce platform (BSD-licensed) with extensive out-of-the-box support for complex B2B, multi-vendor marketplaces, and multi-tenant architectures, supported by an official TypeScript storefront SDK and Next.js starters. Rank assumes a team prioritizing decades of battle-tested commerce edge-case handling over a TypeScript-native backend.

Rank assumes a team prioritizing decades of battle-tested commerce edge-case handling over a TypeScript-native backend.
Where it falls shortper Gemini The core commerce backend is written entirely in Ruby on Rails, requiring Ruby domain knowledge for backend extensions and data modeling; not for full-stack TypeScript teams wanting a unified single-language stack across client and server.

TypeScript/GraphQL headless commerce with strong content-plus-catalog modeling and a good Node/TS SDK, well-suited to content-rich, product-storytelling storefronts where PIM-style flexibility matters.

Claude TypeScript/GraphQL headless commerce with strong content-plus-catalog modeling and a good Node/TS SDK, well-suited to content-rich, product-storytelling storefronts where PIM-style flexibility matters.
Where it falls shortper Claude SaaS-hosted rather than self-hostable open source, smaller ecosystem and mindshare, and less proven for heavy transactional/checkout-complex operations than the top three.

Just missed the top 5
Claude Commerce Layer — excellent typed API-first headless commerce and JS SDK, but a commercial SaaS, not an open-source framework you run · Sylius — very mature and extensible, but PHP/Symfony — wrong language for a TypeScript team
Gemini Mailchimp Open Commerce — discontinued and archived, making it an obsolete choice for active production deployments despite its Node.js roots · Payload CMS — a premier TypeScript-native headless CMS with e-commerce templates that missed the list because it lacks specialized core commerce engines like multi-warehouse inventory reservation and complex promotion calculation out of the box
